- precalculate if a sector's floor and ceiling plane overlap. This avoids rechecking this for each single call of hw_FakeFlat.
- vertices must be marked dirty every time they change after map setup. That means that ChangePlaneTexZ must do this as well, because it cannot rely on interpolation taking care of it.
- Having a 'dirty' argument for SetPlaneTexZ's ZScript version makes no sense. If the value changes from the script side the vertices must always be marked to be recalculated.

* this has to be disabled for missiles which should explode instead of stepping up.
* interpolation adjustment was not correct
* it could crash because the target portal group could be retrieved from a non-portal sector.

This can only happen if some thing gets placed somewhere it doesn't physically fit in and as a result of the floor move would be pushed into an even more invalid place.

For some files that had the Doom Source license attached but saw heavy external contributions over the years I added a special note to license all original ZDoom code under BSD.
This is an incredibly costly way to do a debug check as it infests the entire VM design from top to bottom. These tags are basically useless for anything else but validating object pointers being passed to native functions (i.e. mismatches between definition and declaration) and that simply does not justify a feature that costs execution time in non-debug builds and added memory overhead everywhere.
Note that this commit does not remove the tags, it only discontinues their use.
Both files can now be included independently without causing problems.
This also required moving some inline functions into separate files and splitting off the GC definitions from dobject.h to ensure that r_defs does not need to pull in any part of the object hierarchy.
The entire setup was quite broken with each item using its own activation result and the ones of the subsequent items in the list as the return value.
This rendered the STANDSTILL check in the main function totally unpredictable because the value it depended on could come from any item in the list.
Changed it so that the main dispatcher function is part of sector_t and does the stepping through the list iteratively instead of letting each item recursively call its successor and let this function decide for each item alone whether it should be removed.
The broken setup also had the effect that any MusicChanger would trigger all following SecActEnter specials right on msp start.
There are a few which require explicit native construction or destruction that need to be exported to the VM, e.g. FCheckPosition.
The VM cannot handle this directly, it needs two special functions to be attached to handle such elements.
- disabled the Build map loader after finding out that it has been completely broken and nonfunctional for a long time. Since this has no real value it will probably removed entirely in an upcoming commit.
- made ModifyDamage calls iterative instead of recursive. With going through the VM they'd be too costly otherwise.
- small optimization: Detect empty VM functions right when entering the VM and shortcut them. This is to reduce the overhead of virtual placeholders, which in a few cases (e.g. CanCollideWith and ModifyDamage) can be called quite frequently.
